How to Diagnose and Check the Coil on Your Lawn Mower- A Comprehensive Guide

How to Check Coil on Lawn Mower

Lawn mowers are essential tools for maintaining a well-manicured garden, but like any mechanical device, they require regular maintenance to ensure they operate efficiently. One of the critical components of a lawn mower is the coil, which plays a vital role in the ignition system. In this article, we will guide you through the process of checking the coil on your lawn mower, ensuring that it is functioning correctly and safely.

Firstly, it is important to understand the role of the coil in a lawn mower. The coil is an electromagnetic device that transforms the low-voltage electrical current from the battery into a high-voltage current required to ignite the fuel-air mixture in the engine. A faulty coil can lead to inefficient performance or even prevent the lawn mower from starting altogether.

To check the coil on your lawn mower, follow these steps:

1. Safety First: Before you begin, ensure that the lawn mower is turned off and disconnected from the power source. This is crucial to prevent any accidents or electrical shocks.

2. Locate the Coil: The coil is typically located near the spark plug on the engine. It is a cylindrical device with two wires connected to it, one going to the spark plug and the other to the ignition module or distributor.

3. Inspect the Wires: Check the wires connected to the coil for any signs of damage, such as fraying, cuts, or corrosion. If you notice any issues, replace the wires immediately to avoid any potential problems.

4. Test the Coil: To test the coil, you will need a multimeter. Set the multimeter to the ohms setting and connect the probes to the two terminals of the coil. A healthy coil should show a specific resistance value, which can vary depending on the make and model of the lawn mower. Refer to the manufacturer’s manual for the correct resistance value.

5. Compare with Specifications: If the resistance value is outside the specified range, the coil may be faulty and need to be replaced. Keep in mind that a weak coil may still show a resistance value within the acceptable range but may not perform as expected.

6. Replace the Coil: If you determine that the coil is faulty, you will need to replace it. Purchase a new coil that is compatible with your lawn mower model and follow the manufacturer’s instructions for installation.

7. Reassemble and Test: Once the new coil is installed, reconnect the lawn mower to the power source and test it to ensure that it starts and runs smoothly.

By following these steps, you can effectively check the coil on your lawn mower and ensure that it is in good working condition. Regular maintenance not only prolongs the life of your lawn mower but also ensures that it operates safely and efficiently.
